A suitable hollow water motor rotor designated, generally, as 29, having a suitable centrally arranged bearing 35 is rotatably mounted upon the motor stud Hi. The rotor'29 is contained within the separable motor shield, or housing, and there is provided an annular space 36 between the rotor 20 and the skirts of the motor shield, or housing, and there are provided spaces 31 and 38 between the rotor and the upper and lower walls of the motor shield, or housing.

The rotor 20, in the embodiment thereof, as illustrated, includes a central hollow body portion 39 having the upper and lower bosses 4|] and 4|, respectively, for receiving the bearing 35 which is provided with a plurality of water outlet openings 34 leading through openings l2 in the stud H) to. the hollow body portion 39. A plurality of hollow arms 43 radiate from the hollow body portion 39 and each arm is provided on its trailing side wall adjacent the free end thereof with a suitable Water nozzle 44 through which Water is delivered in a small jet, or stream and directed against the inner wall of the skirt of the upper motor shield to cause rotation of the rotor 2!] counter clockwise.

.A suitable cap 45 is suitably fixed to the upper rotor boss 49 and the lower end portion 46 thereof is receivable in the bore, or opening of the boss 32 of the upper motor shield member 22. The cap 45 is provided with a shoulder 41 to rest on the end face of the upper shield boss 32. The above arrangement leaves the separable motor shield free to rotate between the shoulder 41 of the cap 45 and the conduit boss 8.

A suitable pinion gear 48 is fixed to a stud 49 directed upwardly from the cap 45. The pinion gear 48 meshes with a suitable gear 59 fixed to the lower end of a suitable rust-proof bushing 5| mounted for rotation on an upright stationary shaft, or stud 52 supported by, and suitably fixed to a head 53 at the free end of a horizontal arm 54 integral with the upper end of the bracket I.

A suitable lever-arm 55 is detachably connected at one end, with the bushing 5| above the gear 50 and it is locked against displacement on the bushing by means of a suitable fastening device such, for instance, as a setscrew 56 so as to rotate as a unit with the bushing 5| and gear 59. The outer free end of the lever-arm 53 is provided with a suitable vertically disposed rust-proof bearing 5'! and a lateral ear 58 having a vertically disposed opening59. V

A suitable rust-proof bushing 60 is carried by thestud 52 above the bushing 5|, and the bushing is detachably fixed to the stud 52 by suitable fastening means such, for instance, as a set-screw 6|.

A suitable gear 62 is suitably fixed to the bushing 69 so as to become stationary with the bushing 5| and the stud 52.

A suitable gear shield designated, generally as 53 having a centrally arranged boss 64, is provided with a rust-proof bearing 65 to receive the upper end of the stud 52 to rotatably support the gear shield 63. The boss 54 is seated upon the upper face of the bushing 60 fixed to the stud 52. The gear shield 53 is held from upward displacement upon the stud 52 by means of a suitably headed screw 66 carried by the upper end of the stud 52.

The shield 63 is provided with a top plate 51 having a suitable skirt 58 and also including a suitable boss 69 adjacent the edge of the plate 51 of the shield. The plate 6'! of the shield 63 is provided with a depending pin 10 adiacent the boss 59 adapted'to be received in the bearing 51 in the ear opening 59 on the leverarm 55 to cause rotation of the gear shield 53, as will be hereinafter more clearly apparent. The boss 59 is provided with a central opening to receive a vertically disposed rust-proof hearing 1|, in which a shaft 12 is rotatably mounted. The lower end of the shaft 12 is provided with a bushing 13 which is detachably fixed to the shaft 72 by means of suitable fastening device, such, for instance, as a set-screw 14. A suitable pinion gear 15 is suitably fixed to the lower end of the bushing 13 so as to rotate the bushing l3 and the shaft 12 through an intermediate pinion gear I6 mounted for rotation on a shoul der screw 11 carried by the lever-arm 55 and in mesh with the stationary gear 62.

A plate 78 is detachably secured to the upper face of the central boss 64 on the gear shield 53 by suitable fastening devices such, for instance, as screws 79. The plate 18 is provided with an upright shank, or stud 89 to which is suitably and detachably connected a socket member 8| carried by the lower end of a wire core 82 from which brush bristles 83 radiate and which serve toforma brush designated, generally as 84, to wash the inside of a glass shown as mounted in an inverted position on the brush and adapted to be held in the hand of an operator. The brush 84 is adapted to rotate with the gear shield 63.

The upper end of the rotatable shaft I2 projects upwardly beyond the upper face of the gear shield boss 69 and carries a washer 85, and the shaft 12 terminating above the washer 85 is of a relatively larger diameter to provide an upright shank 81 to which is detachably connected a socket member 88 carried at the lower end of a wire core 89-, from which brush bristles 99 radiate. This arrangement serves to form a brush 9| to wash the outside of the glass 85. The brush 9| not only rotates, but simultaneously revolves around the brush 84 rotated by the shield 63, and upon which brush 84 the glass is held in an inverted position.

The shank 80 on the shaft 52 may be provided with a cross-pin 92 with projecting ends thereof receivable in bayonet slots 93 in the brush socket 8| for detachably connecting the brush socket 8| with the upper end of the brush supporting stud 80, and the shank 8'! of the shaft 12 ma likewise be provided with a cross-pin 94 with projecting ends thereof receivable in bayonet slots 95 in the lower end of the brush socket 88 for detachably connecting the brush socket 88 with-the shank 81 of the supporting shaft 12. Y

Water may be sprayed against the brushes and against a glass being cleaned from suitable pipes, or conduits 95 and 91 leading from a pipe 99 which may be valve controlled as at 99 and connected, if desired, with the water conduit 2 which serves the Water motor. I

The operation of the glass Washing device,'is as follows:

As water, under pressure, is admitted to the rotor 29, it is discharged therefrom throughthe nozzles 44 against the skirts of the motor shield members 2| and 22, which causes the rotor 20 to rotate counter clockwise and thereby turn the pinion gear 48 counter clockwise in mesh with ear 50, which is turned clockwise and turns the lever-arm 55 clockwise, and its pin connection 79 with the gear shield 63 turns the gear shield clockwise. The intermediate pinion gear 76 supported by the lever-arm 55 turns clockwise in mesh with the stationary gear 62 as it moves with the gear shield 63, thereby turning the pinion gear 15 in mesh with the intermediate pinon gear 76 counter clockwise, causing the shaft 72 and the .brush 9| supported by the shaft shank B! to rotate counter clockwise as the brush 9! revolves around the brush 84 during rotation of the gear shield 63. Thus, it will be clearly apparent that a glass 85 held on the brush 84 will be washed on the inside by the brush 84 and on the outside by the brush 9 l.

The many advantages of the herein described invention will readily suggest themselves to those skilled in the art to which it appertains.
